pub fn current_address(&self) -> SocketAddr

Get the current validated address.

pub fn on_receive(&mut self, from: SocketAddr, bytes: usize)

Record bytes received from an address.

pub fn on_send(&mut self, to: SocketAddr, bytes: usize)

Record bytes sent to an address.

pub fn can_send(&self, to: SocketAddr, bytes: usize) -> bool

Check if we can send bytes to an unvalidated address (anti-amplification).

pub fn validate_address(&mut self, addr: SocketAddr) -> bool

Validate an address after receiving an authenticated frame from it.

Returns true if migration to this address is allowed.
